This month I meet some very polite deer who have a special way of asking for food. I discover why some plant nectars contain poisonous toxins. And in the scientific spark, I talk to Iain Couzin from the Max Planck Department of Collective Behaviour. Iain tells me what sparked his interest in becoming a scientist, and how, if his teachers had had their way, he might have been doing something entirely different.
